(English) New Zealand hit by second strong quake

An earthquake measuring 6.3 in magnitude has hit New Zealand’s South Island, hours after an initial quake killed two people.

The new tremor struck at 13:45 local time (00:45 GMT) at a depth of 10km (6 miles), northeast of Christchurch.

A 7.5-magnitude quake, with the same depth, had  hit the same area just after midnight,  triggering tsunami warnings.

A large river dammed up by a landslide has now breached its banks sending a “large wall of water” downstream.

Residents around the Clarence River – one of the largest on South Island – were being urged to move immediately  to higher ground.

There have been hundreds of strong aftershocks, causing power shortages and cuts in water supply, since the initial quake.

 GeoNet,  a government-funded project monitoring earthquakes, said the first earthquake was actually two related tremors, and that aftershocks would continue over the next few months.

As the aftershocks keep coming, Kiwis up and down the country are sharing the same emotions.

Exhaustion from a sleepless night, concern for those still cut off from communication, and sadness for the two people who lost their lives. But there is also real relief.

This earthquake was greater in magnitude than 2011’s Christchurch tremor, but it didn’t bring the same level of devastation.

The cost of rebuilding will be huge – major parts of New Zealand’s infrastructure have been twisted and snapped out of shape.

But as is often the case when disaster strikes, New Zealand’s people have pulled together, checked on their neighbours and offered each other a safe haven.

Authorities have spent the night and day rescuing and evacuating residents along the east coast.

New Zealand media reported that a 100-year-old woman and her daughter-in-law were  pulled out alive,  from their home in the town of Kaikoura, after the house collapsed in the first earthquake. The younger woman’s husband died.

A woman also died at Mount Lyford, southwest of Kaikoura, though there are reports she may have died from an existing medical condition.

Waves of around 2m (6.6ft) hit the coast shortly after the first earthquake. Authorities have since lifted the tsunami alert, but are still warning people to stay away from the shoreline.

Residents in Christchurch and surrounding towns have rushed to stock up on basic supplies. Some schools in the affected area have remained closed on Monday.

Kaikoura, a popular tourist destination, saw its main road blocked by landslides, with telecommunications, water and power supplies cut off.

The military and fire service have dispatched teams in helicopters to the town, and some people are being airlifted out.

 The New Zealend Herald shared images of three cows left stranded on a tiny island after the surrounding earth collapsed from landslides near Kaikoura.

Prime Minister John Key told reporters that he believed the number of fatalities would remain low, while civil defence minister Gerry Brownlee said damage to infrastructure appeared to be the biggest problem.

One expert told TVNZ that the low number of fatalities may have been due to the fact that the first quake struck in the middle of the night.

“People were safe in their homes, homes might get damaged but they’re safer for the people inside,” said Ken Elwood from the University of Auckland.

The quake was also felt in Wellington on the North Island, where the city’s central business district (CBD) remained quiet on Monday as workers cleared debris and checked buildings.

Resident Adam Roland told the BBC: “The CBD’s been closed off so most people are either working from home or not working today.”

GeoNet said the first quake was the strongest to have hit New Zealand since a 7.8-magnitude earthquake in 2009 in a remote area of the South Island.

New Zealand lies on the Ring of Fire, the fault line that circles virtually the entire Pacific Rim bringing frequent quakes and volcanic eruptions.

Christchurch is still recovering from a 2011 earthquake that killed 185 people and destroyed the city centre.
